This waterproof boot for women features a mixed-material upper made from premium Better Leather, sourced from a sustainable tannery-rated silver for its environmental processes and durable ReBOTL™ material. The durable ReBOTL™ material contains at least 50% recycled plastic and is also present in the lining. Add to that our GreenStride™ comfort sole made from 75% renewable materials, including responsibly sourced sugar cane and natural rubber, and a rubber outsole with lugs for better traction.
